Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a submerged block that is installed and used on the seabed, and more specifically to a submerged block that is a fisheries cooperative type and can also be configured as a submerged dike.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, various blocks such as fish reef blocks for fish and aquaculture blocks for abalone fisheries such as aquaculture blocks have been proposed as submerged blocks to be installed on the sea floor and are provided for the convenience of users. There is.

[0003] By the way, these submerged blocks are usually configured only for fish or only for surf fishing, and therefore, for example, fish reef blocks are not suitable as aquaculture blocks for surf fishing due to their too large voids. Not only that, but because of its shape, the nets of fishing boats are caught, and the emergence of a submerged submersion block, which is a combination of fish reef blocks and aquaculture blocks, has been long awaited.

On the other hand, it is also proposed to add a fish reef function or the like to a breakwater structure such as a submerged breakwater used for protection of the coast to achieve a multifaceted effect. The current situation is that no specific proposal has been made.

[0005]

[Means for solving the problem]

 Therefore, in this invention, a void is provided in a part of the concrete lattice-shaped fish reef main body having a trapezoidal cross section, and the aquaculture block body mainly for raising fry and fry is attached to this void. In addition, by forming each side surface of this lattice-shaped body flat, it is possible to combine the fish reef function and the aquaculture function depending on the conditions of its subsidence. The structure of the breakwater structure is designed to be easy.

In this case, it is preferable that the void portion provided in the lattice-shaped fish reef main body is formed in a rectangular parallelepiped shape and the aquaculture block body is formed by filling natural stone inside the steel frame member. By exposing a metal member to the outside of the coral reef body, it is possible to preferably neutralize the alkalinity of the concrete as a raw material.

[0007]

[Action]

 In this invention, the aquaculture block has a space suitable for growing juvenile juveniles by adjusting the voids of the fish reef body by mounting and arranging the aquaculture block body in the voids provided in a part of the lattice fish reef body. Type block is suitable, and each side of the grid-like fish reef body is flat, which is convenient for constructing structures in water, and also has the disadvantage of catching fishing boat drift nets. It can be avoided.

【Example】

 A preferred embodiment of the sinking block according to the present invention will now be described in detail with reference to the accompanying drawings.

That is, the submerged block 10 according to the present invention comprises a fish reef block main body 12 made of concrete or a reinforced concrete material in a lattice shape, and a fish reef block main body for the purpose of cultivating fry and juveniles of seafood. It is basically composed of a culture block body 14 which is mounted and arranged at a predetermined position of 12 (see FIGS. 1 and 2).

The fish reef block main body 12 is formed by vertically and diagonally connecting an upper frame member 16 formed in a lattice shape and a similar lattice-shaped lower frame member 18 set to be slightly larger than the upper frame member 16. By connecting via the member 20, the cross-sectional shape is a trapezoid and a low-height quadrangular pyramid, and a rectangular parallelepiped void portion 22 is provided at the center of the top surface of the fish reef block body 12. Has been.

The fish reef block main body 12 is integrally formed by casting concrete in-situ in a land-based manufacturing yard. At this time, the upper frame member 16, the lower frame member 18, and the connecting member 20 are formed. By winding wire mesh, punching metal, etc. on the outside and exposing these metal members 24 to the outside, the alkalinity of the concrete, which is the material, can be neutralized, so the fishery reef function is also included. This is preferable because the function as a block can be improved (see FIG. 3). In this case, needless to say, when the fish reef block body 12 is made of reinforced concrete, a part of the reinforcing steel bar arranged inside the fish reef block body 12 may be exposed as the metal member 24.

On the other hand, the aquaculture block body 14 has various sizes inside a steel frame member 26 that is sized so that it can be fitted exactly into the space 22 formed in the center of the top surface of the fish reef block body 12. It is formed by filling a large number of natural stones 28 to provide a space suitable for juveniles and juveniles. Then, by mounting and arranging the aquaculture block body 14 in the void portion 18, it is configured as a fishery cooperative submerged block 10 having a trapezoidal sectional shape as a whole and each side surface including the top surface being flat. It

In the submerged block 10 according to the present invention configured as described above, the aquaculture block body 14 is attached to the void portion 22 of the fish reef block main body 12 according to the installation conditions and the environment. For example, as shown in FIG. Although it is used in combination, the aquaculture block body 14 suitable for the growth of juveniles and juveniles is provided in the block body 12 as a fish reef with large voids, which can be suitably used as a fisheries cooperative type block. Is. The submerged block 10 is stable against waves due to its flat surface without protrusions on the outside as a single body or in combination as a whole, and it causes inconvenience such as scratching of the drift net even after the submerged installation. There is no such thing.

In this case, if the submerged block 10 has a trapezoidal sectional shape, the upper frame member 16 and the lower frame member 18 are set to an appropriate shape other than a rectangular shape to diversify the combination, or It is also possible to provide a plurality of voids 22 and set the shapes of these voids 22 and the shape of the culture block body 14 to an appropriate shape. Furthermore, the ratio and height of the fish reef block main body 12 can be changed as appropriate. It goes without saying that it can be set.

In addition, when the submerged dike 30 as an offshore dike structure is constructed using the submerged block 10 according to the present invention, a plurality of submerged blocks are placed on the foundation mound 32 as shown in FIG. Although it is good to stack 10 while combining them, in this case, it is possible to greatly save labor in the work at sea, as compared with the conventional installation of combining a large number of irregular blocks. The installation work can be streamlined. Moreover, the shape itself is stable against waves, and in addition to the original function of the submerged dike, a fish reef effect and aquaculture effect can be expected sufficiently.

[0016]

[Effect of device]

 As described above, the submerged block according to the present invention is not only easy to manufacture because it can be manufactured by cast-in-place concrete, but also the aquaculture block is installed in the void of the main body of the fish reef block. Therefore, the aquaculture block body can also provide a space suitable for growing juveniles and juveniles, and thus a suitable fishery cooperative block can be constructed.

Further, since this submerged block alone has a flat shape with no protrusions on the outer side surface, it is not only stable against waves but also easy to combine, and even after being installed in combination, the fishing net of a fishing boat, etc. Does not cause inconvenience. Furthermore, not only can submerged structures such as submerged blocks that are constructed by combining these submerged blocks be constructed in a stable shape, but their installation work can be performed more efficiently and simply than in the past. It has various advantages such as.

Although the preferred embodiment of the sinking block according to the present invention has been described above, the present invention is not limited to this embodiment, and various modifications can be made without departing from the spirit of the present invention. Of course there is nothing you can do.
